Abstract
The utility model relates to a burner which is applied to various flame heating furnaces. The air and the coal gas of the burner respectively use a pair of honeycomb heat-storage bodies of Ak and Am, and Bk and Bm, and the heat-storage bodies can be bricked in a furnace bottom or a side wall of a furnace body. The direction change of the air and smoke gas uses a four-way change valve, and the direction change of the coal gas and the smoke gas uses four rapid change valves or two three-way valves. The utility model has the advantages that the preheating temperature of the air and the coal gas is high, the energy saving effect is good, the temperature efficiency can reach more than 90 percents, and the heat efficiency can reach more than 80 percents. The installation and the operation are convenient.
Description
The utility model is a kind of burner-a kind of two preheating heat-accumulation combustion devices of coal gas, air that adopt cellular heat storage that are applied to various flame heating furnaces.
Be applied to two preheating heat-accumulation combustion devices of heating furnace, heat storage adopts the flame-proof sphere of φ 10～φ 20mm in the past, and specific area is 100～300m
2/ m
3In the scope.Because the ball specific area is less, makes that whole heat storage is huger, it is all very inconvenient to operate, install, and the gas preheat temperature is also not satisfactory.
The utility model provides the coal gas of a kind of heating furnace with cellular heat storage, the two preheating heat-accumulation combustion devices of air.This device adopts cellular heat storage, and its material is high temperature resistant, and is anticorrosive, Heat stability is good.Make two groups of heat storage switch operations by a cover commutation device, realize the high temperature preheating of coal gas, air, to reach the raising ignition temperature, improve heating quality, fuel-saving purpose.
For achieving the above object, the utility model is realized by following scheme:
A kind of heating furnace is with the two preheating heat-accumulation combustion devices of cellular heat storage coal gas, air, and it is characterized in that: the air of this device, coal gas respectively adopt a pair of cellular heat storage A
k, A
mAnd B
k, B
m, the honeycomb body opening is square, circular, microscler, triangle, corrugated and other is irregularly shaped, and the aperture can be from tens holes be to the hundreds of hole per square inch, and specific area number of ranges level can be from ten to kilobit.Heat storage can be built in the furnace bottom or side wall of body of heater, the air of preheating, coal gas directly spray into the stove internal combustion by the outlet on the furnace wall, also can heat storage be put into one independently casing be built in outside the stove, the air of preheating, coal gas are finished the stove heat supply by the burning of burner tissue.A four-way change-over valve is adopted in air, flue gas commutation, and the commutation of coal gas, flue gas is considered and reduced coal gas communtation loss rate as far as possible, adopts four repid cut-off valves or two triple valves.This device also comprises the control system of valve body, air-introduced machine, air blast and mechanical driving device etc.
Major advantage of the present utility model is: the preheat temperature height of air, coal gas, and only than low about 100 ℃ of flue-gas temperature.Good energy-conserving effect, temperature efficiency can reach more than 90%, and the thermal efficiency can reach more than 80%.Volume little (only be spherical heat storage 1/5～1/3) is installed, operation is all very convenient.
Embodiment:
Fig. 1 is a kind of heating furnace with cellular heat storage coal gas, the two preheating heat-accumulation combustion apparatus structure schematic diagrames of air.
As shown in Figure 1, when the duty I (through the burning of A group heat storage, the accumulation of heat of B group heat storage), cold air is through four-way change-over valve 5, by pipeline through heat storage A
KPreheating.Open repid cut-off valve 2,3 simultaneously, close repid cut-off valve 1,4, coal gas by threeway 6, pipeline and repid cut-off valve 2 through heat storage A
mAir after preheating and the preheating is in the stove internal combustion.Flue gas is respectively through heat storage B
k, B
mDischarge through four-way change-over valve 5 and repid cut-off valve 3, threeway 7 by pipeline.When the duty II, cold air is through postrotational four-way change-over valve 5, by pipeline through heat storage B
kPreheating.Open repid cut-off valve 1,4 simultaneously, close repid cut-off valve 2,3, coal gas by threeway 6, pipeline and repid cut-off valve 4 through heat storage B
mAir after preheating and the preheating is in the stove internal combustion.Flue gas is respectively through heat storage A
k, A
mDischarge through four-way change-over valve 5 and repid cut-off valve 1, threeway 7 by pipeline.Go round and begin again, this kind Regenerative Combustion System is finished the course of work of preheating gas, tissue burning and heat storage accumulation of heat, smoke evacuation.
